RESUMEN
INTRODUCTION: Pelviperineal complications after abdominoperineal resections are tough to treat. None of the available prophylactic methods has proven efficacy besides being technically challenging and expensive to perform. The present study aims to describe the technical details and short-term outcomes using mobilised umbilical ligaments to cover the pelvic inlet. TECHNIQUE: After completing the rectal resection, the bladder with umbilical ligaments is mobilised anteriorly into the space of Retzius until the free edge can reach the sacral midline. Hitching stitches are taken to fix the umbilical ligaments into the new position. Seven consecutive patients had the umbilical ligament flap used for pelvic inlet closure. RESULTS: Cross-sectional imaging on day 30 demonstrated the viable flap in all patients, and the small bowel descent was prevented. None of the seven patients had small bowel obstruction till day 90 after the operation. No patient required re-catheterisation, experienced major complications or wound infections that would necessitate re-intervention. CONCLUSION: Using mobilised umbilical ligaments hitched to the pelvic inlet is a technically safe and feasible procedure to prevent pelviperineal complications after APR.
